Thanks guys, let'* hope they perform as good as they look ahahaha
Tom, I heard nothing but great review about the 13TW5'* in trucks. Couldn't find any with them in a car. So I'm kinda nervous about it. The box is built to specs, and I hope it sounds good
Didn't have time to get screws to mount them in, took me a while to dig up some black screw in my tool box (yes they had to be black to match ahahaha) so I spend an hour fitting them straight, connecting the wires inside the box, mounting the amp on the back of it (for now till I have time to work on a better location for it) and connected the wires from the amp to the box.
Car is already wired up, so tomorrow sometime or saturday I'll remove my current MTX sub and hook this up.
Wish me luck, I think I need it

Also put two in the back of a Toyota Celica which is a hatch back. Also AMAZING!
I am interested to see how they perform not being in the same airspace as the listener, since in both the truck and Celica you are still in the same airspace, but I have no doubt you will be 100% satisfied.

Oh, and I haven't seen any mention of what you are going to amp them with?
I love JL amps, but if I were you and I had to upgrade, I'd throw a 1000Watt Alpine PDX in and call it good. They are rated at 1000Watt but a little birdie told me that with a little extra voltage you can get much more....

fingers crossed lol
yeah they do perform great in open airspace, but in a car i have no idea
as for the amp i'm using the JL GMAX which rated about 1200 rms i believe, which i think should be good
i threw them in the trunk this morning, fitment is okay, much more space so I'm happy!
i havent played with the amp yet, but i lowered the input sensitivity to half and i turned them up, they did hit pretty damn good, and very loud, but i gotta admit nowhere near as good as a W7, but again i still didnt tune it right, i had the W7 tunes really really good
this tells you the size of the box

and heres a sneak peak in the trunk

Hello space!!
PS. if anyone can give me a hand on how to properly tune them that would be awesome, because honestly i dont know much about tweeking them to the right specs
